Does posttraumatic stress predict frequency of general practitioner visits in parents of terrorism survivors? A longitudinal study

Background: Life threat to children may induce severe posttraumatic stress reactions (PTSR) in parents. Troubled mothers and fathers may turn to their general practitioner (GP) for help. Objective: This study investigated frequency of GP visits in mothers and fathers of adolescent and young adult terrorism survivors related to their own PTSR and PTSR in their surviving children.
